Constructional features:

Casing: Latest casing techniques ensure smoothness of hydraulic passages resulting in high efficiency and reliability under hazardous conditions. The delivery flange is vertical. The suction flange can be oriented left or right viewed from driving end.

Impeller: The enclosed impellers of the radial flow type are provided with balancing holes to balance the hydraulic axial thrust. The rotating elements are statically and dynamically balanced.

Shaft: The high tensile steel shaft accurately machined and ground is supported by antifriction bearings that take the residual axial thrust and prevent axial float or radial run out. The shaft is protected by shaft sleeve from wear in stuffing box area.

Stuffing Box: The stuffing box can be sealed by gland packing or by mechanical seal with minor modification. While pumping high temperature liquids from 90ºC to 140ºC, cooling jacket is provided for the stuffing box.
